The XBU55 is built to exceed expectations with a 30-lb steel flywheel system working in conjunction with an 8-groove poly-V belt drive train. Comfort is ensured with oversized, self-balancing foot pedals and the large, cushioned seat that is easily adjusted up, down, fore, and aft. It also features a backrest adjustment that reclines for individual comfort and preference. The bike has a small footprint, and although it is built with extra-heavy-gauge steel tubing, it only weighs 100 lb.Dimensions: 43" x 22" x 54"
